- LEE Flash G1, Good Cost Performance SONOS Flash
High Temperature Operation
SONOS is the device which enables memory functionality trapping electrons in Silicon Nitride film, and the retention life is controlled by optimization of thickness and film properties of oxide and Silicon Nitride films. G1 is able to support operation temperature up to 150C and 20years of data retention life at 150°C.
Large Programming Size enables Short Testing Time
Short Test Time: G1 achieves very short test time for two reasons.
- Extremely low power in program/erase allows tester to program/erase the whole memory mat at once, compare to conventional solution program/erase smaller sections for many many times to program/erase the whole memory mat.
- Sharp Vt distribution in programming will eliminate the requirement for multiple programming and verification, so that programming operation always completes at one time, not in multiple steps, to dramatically reduce programming time.
Short Baking Time
Floadia’s unique memory architecture simplifies Life Time Prediction of the memory cell, which allows chip company to screen devices with shorter baking time.
2-3 Mask adder
G1 requires only 2 to 3 additional masks on standard CMOS process, reducing expensive mask cost to implement NVM feature on your chip. Conventional solution will usually take around 10+ additional masks and uses special manufacturing process.
Re-use of existing IP asset
Unlike normal Flash IPs, our Flash IP does not affect SPICE model of the logic transistors, which means you can utilize existing IPs and assets that has been developed, and will eliminate additional IP investment specific for Flash ICs.
